This is a collection of aphorisms about overthinking. It’s short, to the point, and highly practical. Just like Singer’s book, Tolle does a great job at explaining the techniques you can apply without getting bogged down by its history.

Most of us don’t care about the history of philosophy. We care about the practical application of it. Here’s one of my favorite quotes from the book:

“Whenever you are immersed in compulsive thinking, you are avoiding what is. You don’t want to be where you are. Here, Now.”

I think the Stoics would agree with this as well. Overthinking only exists when you’re too busy chasing your desires or running from your repulsions. In fact, that’s what most of us do all our lives.

We need to find the courage within ourselves to be okay with life the way it is. Don’t wish things were different. Things are the way they are—so stop asking, “why is this happening to me?” Accept it. Only then can you be free of your mind.
